A. General
A well-planned maintenance program will help to avoid unnecessary downtime or costly repairs, promote
safety, and aid boiler inspectors in performing required periodic inspections. An inspection schedule with a
listing of procedures should be established. It is recommended that a boiler room log or record be maintained.
Recording of daily, weekly, monthly, and yearly maintenance activities provides a valuable guide and aids in
obtaining safe, economical and lengthy service from your Cleaver-Brooks equipment. It is important to realize
that the frequency of inspection will depend on variable conditions such as load, fuel, system requirements,
boiler environment, etc.
Shut off electrical power to the boiler when performing any service or maintenance work or work that requires
removal of covers or component parts. Failure to heed this warning could result in electrical shock, serious
personal injury or death.
Good housekeeping practices help maintain a professional appearing boiler room. Only trained and authorized
personnel should be permitted to operate, adjust, or repair the boiler and related equipment. The boiler room
should be kept free of all material and equipment not necessary to the operation of the boiler or heating
system.
Even though the boiler has electrical and mechanical devices that make it automatic or semiautomatic in
operation, the devices require systematic and periodic maintenance. Any “automatic” feature does not relieve
the operator from responsibility. Automatic features do free the operator of certain repetitive chores, thus
providing more time to devote to upkeep and maintenance.
Alertness in recognizing an unusual noise, improper gauge reading, leaks, etc., can make the operator aware
of a developing malfunction, permitting prompt corrective action that may prevent extensive repairs or
unexpected downtime. Any leaks - fuel, water, steam combustion gases - should be investigated and repaired
with all due consideration of the necessary safety precautions.
Preventative maintenance measures such as regularly checking the tightness of connections, locknuts,
setscrews, packing glands, etc., should be included in regular maintenance activities.
